Title: Improvements in or relating to the production of aryl substituted mono-olefines
IPC: C07C4/12
Filed: 1936-10-30
Abstract: Di-vinyl aromatic hydrocarbons are produced by pyrolysis of the corresponding di-alkyl condensation product of an aromatic hydrocarbon and a mono-olefine containing 3 to 5 carbon atoms, one or more products of thermal dehydrogenation of the condensation product being added to the gaseous reaction material. Dehydrogenation reactions are thereby suppressed and demethanation reactions enhanced.  The aromatic hydrocarbon and olefine may be condensed by known methods or with the use of sulphuric acid as described in Specification 486,520.  Pyrolysis is effected at 600-800, preferably 650-750 DEG  C., and preferably at atmospheric pressure or below, with a linear gas velocity in excess of the critical velocity to ensure turbulence.  Diluents such as steam may be present.  The di-vinyl products are used in the production of resins.  Mixtures of mono- and di-alkyl condensation products, e.g. mono- and di-isopropyl benzene, may be used to give mixtures of, e.g. styrene and di-vinyl benzene.  In examples: (1) di-isopropyl benzene and 4 molecular proportions of hydrogen are passed through a copper tube at 675 DEG C.  The product is fractionated to give a fraction containing isopropyl phenyl propylene which is returned to the pyrolysis and a di-vinyl benzene fraction used in resin production; (2) the product of pyrolysis of di-isopropyl benzene and 3 molecular proportions of steam is fractionated to give fractions containing high proportions of di-vinyl products, and a fraction containing isopropyl phenyl propylene and unchanged di-isopropyl benzene which fraction is pyrolyzed in accordance with the invention.

Title: The manufacture of new indophenols and leucoindophenols and new dyestuffs therefrom
IPC: C07D209/08
Filed: 1926-11-27
Abstract: 286,005. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Nov. 27, 1926. Indophenols are obtained by the simultaneous oxidation of 2 : 3 dihydroindol or a substitution derivative thereof and p-aminophenol or by condensing the former with quinone chlorimide or with p-nitrosophenol; on reduction they yield the corresponding leuco-indophenols. In an example, to a hydrochloric acid solution of 1-methyl-2 : 3- dihydroindol a hydrochloric acid solution of paminophenol is added and subsequently also sulphuric acid. The mixture is then introduced into ice cold sodium dichromate and after adding caustic soda is reduced with sodium hydrosulphide. By acidifying and heating, adding common salt and then cooling, the yellow leuco indiphenol separates. In caustic soda solution it rapidly oxidizes to the red indophenol. In further examples leucoindophenols are prepared in the same manner by oxidation of p-aminophenol with 2 : 3-dihydroindol and with 1-phenyl-2 : 3-dihydroindol. According to further examples, 2 : 6- dichlor-4-aminophenol is oxidized together with 1-methyl-2 : 3-dihydroindol and quinone chlorimide is condensed with 1-methyl-2 : 3-dihydroindol. Sulphuretted dyes are obtained by subjecting the indophenols or leucoindophenols prepared as above described to polysulphide fusion. According to an example the indophenol prepared from 2 : 3-dihydro-alpha-phenylindol and p-aminophenol is melted with sodium sulphide, sulphur and alcohol and the whole refluxed. The alcohol and excess sulphur are removed, leaving a product which dyes cotton from a sodium sulphide bath fast violet shades. In further examples the indophenols from 2 : 3-dihydro-alpha-methylindol and 1: 2-dimethyl-2 : 3-dihydroindol are sulphuretted in a similar manner.

Title: Method of producing casting and coating compositions films webs of rollable flexible elastic material sheets bars and mouldings utilising fillers produced from refuse
IPC: B09B3/00
Filed: 1975-07-18
Abstract: In order to prepare these casting compositions, a modified compost is mixed with a curing synthetic resin or synthetic resin mixture, a liquid compost extract and castor oil, glycerol, cobalt salt solution, curing agent and accelerator. The modified compost is obtained by composting refuse by keeping the compost formed in a heatable container together with a solvent in a weight ratio of from 1:2 to 1:4 until ripe and then drying the container contents by heating. The liquid compost extract is obtained by extracting compost, but not the modified compost, with an organic solvent at elevated temperature. Titanium oxide or carbon black may be added to the casting composition. By application to a substrate or introduction into moulds followed by curing, the casting composition can be used to produce mouldings, such as, in particular, films and sheets, but also road surfaces. The mouldings are water-repellent, petrol- and oil-resistant, resistant to acids and lyes, have high abrasion resistance and can easily be machined.

Abstract: 1310718 Recovering sulphur dioxide WELLMAN-LORD Inc 23 June 1970 [18 July 1969] 30352/70 Heading C1A In the process of removing SO 2  from a gas containing it in which process the gas is contacted with an absorbing solution or slurry of sodium, beryllium or lithium sulphite to form a spent absorbing solution containing the bisulphite; the spent absorbent being regenerated to give the sulphite, SO, and water, and being simultaneously evaporated to precipitate the sulphite which is separated to give a mother liquor; the sulphite solid being dissolved in water and recirculated to the absorbing zone; the said mother liquor or major proportion thereof is recycled to the regeneration zone and the weight ratio of bisulphite to sulphite in total of recycled mother liquor and spent absorbing solution is maintained at least at 1 : 1. In Fig. 1 a flue gas containing for example 0À05 to 10 mole per cent of SO 2  is passed into a tower 10 where it is first contacted with a water moistened (via lines 12) mass 11 which removes the dust particles and more water soluble constituents. It then passes upwardly through a zone of discs 14 and rings 13 in which it encounters a descending lean absorbent liquor from line 15. The SO 2 -free gas then passes to exhaust through a demisting zone. The spent absorbing liquor removed at 17 is part recycled via 18 and part fed to the desorber via line 19, 21. SO 2  and steam pass from the top of the desorber to rectification, and from the bottom, a sulphite slurry is part recycled via calandria 24 in which it is indirectly steam heated and part is centrifuged, the mother liquor passing via line 28 to a receiver from which it passes via lines 31, 20 to be mixed with the spent absorbent just before it enters the desorber. From the base of the centrifuge the crystalline sulphite is dissolved in water in a vessel to which make up water and solution, e.g. NaOH, containing make up metal values is added, the resulting liquor being recirculated via line 15 to the absorbing stage. To diminish the accumulation of sulphate values in the circulating liquors, an oxidation inhibitor e.g. hydroquinone in an amount of 0À01 -to 0À3 wt. per cent, may be added to the absorbent and mother liquor, and liquor may be withdrawn from the cycle by purge lines 32 and 30. In an alternative embodiment, Fig. 2 (not shown), the single desorber is replaced by a plurality of distinct vessels each maintained at a different pressure, the used absorbent being conducted in parallel feed to these vessels, which are staged in multi-effect relationship so that the overheads from all but the lowest pressure vessel are brought into heat exchange with the solution being desorbed in the vessel of next lowest pressure. A temp. up to 300‹ F. may be used in the desorbing zone. Various preferred concentrations of sulphite and bisulphite are given.

Abstract: 731,183. Moulds for making bricks. ROBERTS, W. Dec. 24, 1953 [Dec. 2, 1952], No. 30505/52. Class 87 (2). A mould box for use in making bricks in a compression moulding machine comprises a pair of side walls 3, 4 and a pair of end walls 6, 7 interjoined to form a box open top and bottom, and each wall has inwardly projecting flanges extending at least partly along upper and lower edges to provide side and end recesses for a set of replaceable liners and at each joint a flange part of one wall overlaps a complementary non-flanged region of the adjoining wall. As shown, the mould box is divided into four compartments by a division plate S and two transverse plates 8, 9. The side plates have inward flanges 3a, 4a and the plates 5, 8, 9 have flanges 5a, 8a, 9a on both sides, all these flanges extending the length of the plates. The inward flanges 6a, 7a of the end plates extend along part only of their lengths only, leaving unflanged regions to be overlapped by the flanges of the side plates. The preferred material is mild steel. The liners which fit in the recesses formed by the flanges are removable for reacfing, and if a liner has been refaced, shims may be inserted when the liner is replaced, to allow for its reduction in thickness. Recessers are formed in the side liners for spigots on the ends of the transverse division plates. These transverse plates, and the end plates, may be of different lengths, resulting in the compartments of the box being of two different sizes. The flanges may be interrupted. Holes 11 may extend through the end plates, for lifting rods. The bolts to which hold the mould box assembly together also pass through the plane of the end plate.
